Made in USA the Heavy Duty Chair Mat for Hard floors 1150 x 1350mm is designed to protect hard floors. The mat is suitable for use on timber floors, vinyl floors & concrete and other hard surfaces. The Transparent finish allows visibility through the mat and means that your existing floor covering shows through the mat. Made from pure PVC, toxic plasticisers which are used in other chair mats are not used in the Heavy duty mat making them safe to use in confined spaces and around children. This PVC is extruded to give the chair mat an ultra-clear surface. It is critical to ensure that the hard floor surface underneath the Heavy Duty Chair Mat is completely clean and dry before laying down the mat and ongoing. This will help to prevent the mat slipping on dirt particles and also causing damage to your floor coverings. This mat can be mopped clean occasionally with a damp cloth, swept or vacuumed. The full details on how to maintain this product are detailed in the cleaning instructions tab. This mat is suitable for commercial use and is covered by a 12 year warranty.
